CS271242B1 - Method of production of hollow glass products and equipment for production arrangement - Google Patents

Abstract

The solution applies to a method of production of hollow products from glass. The bulb is centrifuged and it is transmitted into the blowing mould when rotating and tilting, and, as a result, the final product is moulded into the blowing mould by means of air pressure and vacuum blowing. The device for the application of this method consists of a mould for centrifugal casting, transmission mechanism and at least one blowing mould in each centrifugal station.
